Karen I think several (at least) women here have had them. I did, and the Dr aspirated it two or three times. i think he removed one of the drains too early also. I DO think it is better to just leave it alone for a while to see if it will reabsorb on it's own though. There was an area of mine that never did seem to go back to normal. Of course I ended up having the recon done two more times anyway.
I think they happen quite often with mastectomies, like you said. I am sure you will hear from others too.
Hope it all goes well for you!
It's only when we truly know and understand that we have a limited time on earth -- and that we have no way of knowing when our time is up, we will then begin to live each day to the fullest, as if it was the only one we had.
